That's right. The issues you mentioned are very important. We usually think of making a profit through trading but we do not focus on risky management. As a result, the loss in our portfolio is huge. If we can keep this risk management in proper order then our overall profit will be higher then getting trading profit. Once a trade is lost, it takes a long time to recover, so risk management is much important.
well, the OP has a brief, but insightful explanation. however, strategic management in trading is important. sometimes, people only see the percentage, but don't see the actual value of the asset. Because of this, the risk-reward ratio needs to be considered.
Personally, I do a strategy that emphasizes minimal risk. like logging in on $100 total assets, and when the total assets drop to $85, I'll pause and plan back, then re-enter with $100 when the time comes. however, for an increase in total assets, I will hold that until I am satisfied with the result.
